ST STSPIN32F0三相BLDC马达驱动方案
ST公司的STSPIN32F0是系统级封装器件,采用不同驱动模式提供三相BLDC马达驱动方案.器件嵌入了三个半桥功率MOSFET或IGBT栅极驱动器,内部的DC/DC降压转换器提供3.3V,用来给MCU和外部元件供电,内部的LDO线性稳压器给栅极驱动器供电.工作电压8-45V,主要用在厨房机器人,手持真空吸尘器,干手机,无人机,电动工具,工业和教育机器人,家用电器和空调风扇.本文介绍了STSPIN32F0主要特性,框图和应用案例,以及评估板STEVAL-SPIN3201主要特性,电路图和材料清单.
The STSPIN32F0 is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes.
The STSPIN32F0 is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes.
It embeds a triple half-bridge gate driver able to drive power MOSFETs or IGBTs with a current capability of 600 mA (sink and source). The high- and low-side switches of same half-bridge cannot be simultaneously driven high thanks to an integrated interlocking function.
An internal DC/DC buck converter provides the 3.3 V voltage suitable to supply both the MCU and external components. An internal LDO linear regulator provides the supply voltage for gate drivers.
